What a great idea! Thanks! Never would have thought about the laminating!I prevent saggy bottoms on my bags by using an insert. You can have them custom made in the size you need or make them yourself. If you have the means to cut plexi glass or a thick plastic those are good inserts. I don't have a way so I use a thick piece of cardboard....I actually use Coach shipping boxes, they work great and I use the piece with the horse and carriage logo on it for my Coach bags. Once I have the right shape I cover it with laminating sheets. No more saggy bottoms.
